“For we are the true circumcision, who worship in the Spirit of God and glory in Christ Jesus and put no confidence in the flesh.” (4:2)
Always remember the power of our Salvation is the victory of Christ, who removed the sting/curse of death/sin; teaching us the way to live (2:5-7) and giving us newness by His Spirit. That is what differentiates His people from others: His transformation power.
This looks like the applications in chapter four: rejoicing always, being gentle, choosing prayer over anxiety, having peace and the perspective to be content in every circumstance.
It’s not about mustering the strength to police ourselves and others, it’s walking in the truth of the gospel. That’s why Paul encourages this:
“Whatever is true, whatever is honorable, whatever is right, whatever is pure, whatever is lovely, whatever is of good repute, if there is any excellence and if anything worthy of praise, dwell on these things.” (4:8)
Fill your life with truth. Seek it out. Study the Word. Don’t let fear or desperation become a motivator for any aspect of life. This is a great reminder for all of us.
